A 3D MOF based on Adamantoid Tetracopper(II) and Aminophosphine Oxide Cages: Structural Features and Magnetic and Catalytic Properties.

ABSTRACT: This work describes an unexpected generation of a new 3D metal-organic framework (MOF), [Cu₄(μ-Cl)₆(μ₄-O)Cu(OH)₂(μ-PTA═O)₄]_n·2nCl-EtOH·2.5nH₂O, from copper(II) chloride and 1,3,5-triaza-7-phosphaadamantane 7-oxide (PTA═O). The obtained product is composed of diamandoid tetracopper(II) [Cu₄(μ-Cl)₆(μ₄-O)] cages and monocopper(II) [Cu(OH)₂] units that are assembled, via the diamandoid μ-PTA═O linkers, into an intricate 3D net with an nbo topology. Magnetic susceptibility measurements on this MOF in the temperature range of 1.8-300 K reveal a ferromagnetic interaction (J = +20 cm^-1) between the neighboring copper(II) ions. Single
